I trying to run a multi objective optimization problem with Gamultibj, I got that error, Can anyone help me
options = optimoptions(@gamultiobj,'PlotFcn',@gaplotpareto);
[x,Fval,exitFlag,Output] = gamultiobj(@functionmulti,nvars,A,b,Aeq,beq,lb,ub,options);
Error using optimoptions (line 114)
Invalid solver specified. Provide a solver name or handle (such as 'fmincon' or @fminunc).
